A Real-world HCM-cohort Trial
A Multicenter, Prospective, Real-world Study on Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy (HCM) is a genetically mediated myocardial disease predominantly caused by pathogenic mutations in sarcomeric protein genes and characterized by asymmetric left ventricular hypertrophy. Patients with HCM commonly present with dyspnea, chest pain, and exercise intolerance. Sudden cardiac death, progressive heart failure, and thromboembolic events remain the leading causes of mortality and morbidity, substantially impairing quality of life and increasing healthcare burden.
Despite advances in understanding the pathophysiology, diagnosis, and management of HCM, significant challenges persist, including etiological heterogeneity and underdiagnosis. At present, dedicated and systematic HCM databases remain lacking in China. Establishing a nationally HCM cohort and disease-specific database is therefore of considerable importance. In alignment with the goals of the "Healthy China 2030" initiative and supported by advances in medical big data technologies.
This study aims to construct a comprehensive HCM cohort, evaluate contemporary diagnostic and therapeutic practices and patient prognosis, identify relevant risk factors, and ultimately improve the overall management of patients with HCM.

Beschrijving
Inclusion Criteria:
- Meet the clinical diagnostic criteria for HCM*;
Patients who understand the purpose of this study, voluntarily participate in the trial and sign the informed consent form, have good compliance, and are willing to undergo clinical follow-up.
- Clinical diagnosis of HCM is defined as left ventricular wall thickness ≥15mm at any position during diastole by.echocardiography or CMR (≥13mm if there is a family history of HCM or positive cardiac genetic testing), and other secondary factors (such as severe hepertension, aortic stenosis) causing myocardial hypertrophy are excluded.
Exclusion Criteria:
- Metabolic syndrome or hypertrophic cardiomyopathy-like syndromes associated with left ventricular hypertrophy, such as amyloid cardiomyopathy, sarcoidosis, Fabry disease, Danon disease or Noonan syndrome;
- Severe systemic hypertension and/or severe aortic stenosis (<1cm²);
- Comorbid malignant tumors;
- Comorbid with other end-stage diseases with an expected lifespan of less than 3 years;
- Comorbid with mental disorders;
- Currently participating in other clinical trials and not reaching the primary endpoint.
